| Luschka's tonsil | A collection of more or less closely aggregated lymphoid nodules on the posterior wall and roof of the nasopharynx, the hypertrophy of which constitutes the morbid condition called adenoids. Synonym: tonsilla pharyngealis, tonsilla adenoidea, Luschka's gland, Luschka's tonsil, third tonsil. (05 Mar 2000) |

| advanced concepts torus i | <physics> A steady-state toroidal device built primarily for studies of RF heating and RF current drive. Acronym: ACT I (09 Oct 1997) |
| bumpy torus | <radiobiology> I believe this concept tries to combine mirror concepts with toroidal ones. My understanding is that it is essentially a series of mirrors stuck end to end and bent into a ring. - Albert Chou (corrections / enhancements welcome!) (09 Oct 1997) |
| palatine torus | Torus palatinus, an exostosis protruding from the midline of the hard palate. (05 Mar 2000) |
| mandibular torus | Torus mandibularis, an exostosis protruding from the lingual aspect of the mandible, usually opposite the premolar teeth. (05 Mar 2000) |
| compact torus | <radiobiology> Any of a series of axially symmetric fusion configurations having closed flux surfaces (like a tokamak, not like a mirror machine), but having no material objects piercing the core (as do the toroidal field coils of a tokamak). These devices have an inherently low aspect ratio, approximately unity. The most successful variants are the spheromak and the Field Reversed Configuration. See: low aspect ratio, spheromak, field-reversed configuration. (05 Jan 1998) |
| torus | Structure found at the centre of a bordered pit, especially in conifers, forming a thickened region of the pit membrane. When subjected to a pressure gradient, it seals the pit by pressing against the pit border. (18 Nov 1997) |
| torus fracture | A deformity in children consisting of a local bulging caused by the longitudinal compression of the soft bone; it occurs commonly in the radius or ulna or both. Synonym: folding fracture. (05 Mar 2000) |
| torus frontalis | A slight prominence on the frontal bone at the root of the nose. (05 Mar 2000) |
| torus levatorius | The bulge in the lateral wall of the nasopharynx, below the opening of the auditory tube, produced by the levator veli palatini muscle. Synonym: torus levatorius, levator swelling. (05 Mar 2000) |
| torus manus | Archaic term for the carpal bones. (05 Mar 2000) |
| torus occipitalis | An occasional ridge near the superior nuchal line of the occipital bone. (05 Mar 2000) |
| torus uretericus | A fold of mucous membrane extending from the orifice of the ureter of one side to that of the other side. Synonym: plica interureterica, bar of bladder, Mercier's bar, plica ureterica, torus uretericus, ureteric fold. (05 Mar 2000) |
| torus uterinus | A transverse ridge on the back part of the cervix of the uterus, formed by the junction of the rectouterine folds. (05 Mar 2000) |
